When it comes to teaching people, it\'s often the detail that counts and more is always better. Being able to share your ideas and knowledge with a large audience can be difficult but a huge benefit. With the Optoma DC450, you simply position items under the camera, connect it to a projector and show everything on the big screen live as it happens. Information becomes clear and everyone shares your vision. The DC450 features a 8-megapixel sensor, 80X total zoom (10X optical zoom / 8X digital zoom) and up to 30 frames-per-second video (at full resolution) for stunning image quality and performance allowing you to see detail often not visible to the human eye. Take photos or video using the camera function and include them in future presentation - it\'s all so easy. Create more engaging lesson content by easily capturing images, video and audio with the DC450 Document Camera. You can even take a video of a science experiment with the document camera, save it on your PC/Laptop via USB or save to a SD card and use it in your next class and students can record their demonstrations during presentations for later review. The DC450 is powerful, robust and full of useful features that will revolutionize any classroom lessons or meeting room presentations.
